What is this on a Damselfish?

Hey all, I’ve just noticed this white spot on one of my blue damselfish. Just wondering what it could be.

A bit hard to tell but looks like an injury to me. Other fish, possibly liverock, etc. Best of luck

Better pictures can help but I agree it’s likely an injury. Good food and water should help it to heal.
